Nuevas estrategias terapéuticas para tratar la hiperfosfatemia en la IRC: foco en la absorción intestinal / New therapeutic strategies to treat hyperphosphatemia in CRF: focus on intestinal absorption

RESUMEN El manejo de la hiperfosfatemia de los pacientes con insuficiencia renal crónica en diálisis permanece como un desafío. A pesar de utilizar un enfoque multifacético que incluye la restricción dietética, la remoción de fósforo por la diálisis y el uso de quelantes de fósforo, esta estrategia múltiple no logra reducir los niveles de fósforo en más de 2 mg/dl. El control de fósforo de los pacientes en diálisis es fundamental en razón de la relación monotónica entre los niveles séricos de fosfato y el incremento del riesgo cardiovascular. Por lo tanto, hay una necesidad de explorar nuevas estrategias para reducir los niveles séricos de fosfato a niveles normales. Recientes avances en nuestra compresión de los mecanismos que subyacen a la homeostasis del fósforo sugieren que el transporte gastrointestinal del fósforo podría ser un objetivo. Recientemente se han desarrollado inhibidores de los cotransportadores sodio fosfato del intestino y se ha revalorizado el uso de la nicotinamida, en su formulación de liberación prolongada, que también actuaria por ese mecanismo. También se han drogas como el tenapanor, que inhibiendo el intercambiador sodio/hidrogeno isoforma 3 del enterocito, disminuyen la absorción paracelular de fósforo.

ABSTRACT Management of hyperphosphatemia in patients with chronic renal failure on dialysis remains challenging. Despite using a multifaceted approach that includes dietary restriction, phosphorus removal by dialysis, and phosphate binders, these multiple strategies fail to reduce phosphorus levels by more than 2 mg/dL. Phosphorus control in dialysis patients is essential due to the monotonic relationship between serum phosphate levels and increased cardiovascular risk. Therefore, there is a need to explore new strategies to reduce serum phosphate levels to normal levels. Recent advances in understanding the mechanisms underlying phosphorus homeostasis suggest that the gastrointestinal transport of phosphorus could be a target. Inhibitors of intestinal sodium phosphate cotransporters recently developed, and using of nicotinamide, in its prolonged release formulation, which would also act by this mechanism, has been revalued. There have also been drugs such as tenapanor, which, by inhibiting the isoform three sodium/hydrogen exchanger of the enterocyte, decreases the paracellular absorption of phosphorus.

A comparative physicochemical and pharmacological evaluation of dexamethasone sodium phosphate and betamethasone sodium phosphate mucoadhesive gels for the treatment of oral submucous fibrosis in rats

Abstract The present study is aimed to formulate steroidal oral mucoadhesive gels of dexamethasone sodium phosphate and betamethasone sodium phosphate. Six gel formulations each of dexamethasone sodium phosphate and betamethasone sodium phosphate prepared using two different polymers carboxymethyl cellulose sodium and hydroxypropyl methylcellulose, in variable proportions. All the formulations subjected for assessment of various physicochemical parameters and mechanical properties. The formulations BSP5 and DSP5, both containing 1.25 % carboxymethyl cellulose sodium, 1.25 % hydroxypropyl methylcellulose, exhibiting mucoadhesive strength of 12.300 ± 0.004 and 12.600 ± 0.01, adhesiveness of 28.04 ± 00 and 30.02 ± 00, cohesiveness of 28.04 ± 00 and 30.02 ± 00, drug release of 86.869 ± 0.380 % and 88.473 ± 0.457 % respectively were considered as promising ones and were further subjected for stability studies and in vivo study in male albino rats. Formulation DSP5 upon oral application for 4 months in arecoline induced oral submucous fibrosis rats, showed more than 80 % reduction in fibrosis as compared with BSP5 which showed nearly 50 % reduction. These results were concluded on the basis of histopathological profile and weight gain among the experimental animals during in vivo study. Hence, DSP5 by minimizing the painful injuries and morbidities justifies being suitable noninvasive model for OSMF treatment.

Split-dose Bowel Preparation for Colonoscopy: 2 Liters Polyethylene Glycol with Ascorbic Acid versus Sodium Picosulfate versus Oral Sodium Phosphate Tablets / 대한소화기학회지

BACKGROUND/AIMS: Adequate bowel preparation is an essential factor affecting the visibility of colonic mucosa and safety of related therapeutic interventions. The aim of this study was to assess the efficacy, tolerability, and safety of three bowel preparation agents –2 L polyethylene glycol with ascorbic acid (PEGA), sodium picosulfate magnesium citrate (SPMC), and oral sodium phosphate tablet (NaP)– for morning colonoscopy. METHODS: Here, we analyzed the medical records of patients who had taken bowel preparation agents using the split-dose method and undergone colonoscopy in a single hospital. The efficacy of bowel preparation agents was evaluated using the Ottawa bowel preparation assessment tool. The safety and tolerability of the agents were assessed by measuring the renal function and electrolytes prior to and after the procedure as well as by assessing the self-reported questionnaire. RESULTS: Of the 365 patients (PEGA:163, SPMC: 93, NaP: 109), 98.6% ingested more than 90% of the agents. NaP showed an inferior cleansing efficacy, and serum phosphate elevation was significantly higher in the NaP group. However, the satisfaction score was lowest in the PEGA group. Age (odds ratio [OR] 0.96, 95% confidence interval [CI] 0.92–0.99, p=0.04) and preparation agents (OR of PEGA versus NaP 5.0, 95% CI 2.28–10.97, p<0.001) (OR of SPMC versus NaP 2.73, 95% CI 1.22–6.08, p=0.01) were independently associated with bowel preparation success. CONCLUSIONS: According to our analysis, NaP showed an inferior cleansing efficacy compared with PEGA and SPMC, which may be attributed to the complex administration method and lower water intake. However, large-volume ingestion remains unsatisfactory for patients. Detailed bowel preparation instructions could enhance bowel cleansing efficacy.

Randomized Controlled Trial of Sodium Phosphate Tablets versus 2 L Polyethylene Glycol Solution for Bowel Cleansing prior to Colonoscopy / 대한소화기학회지

BACKGROUND/AIMS: Performance of polyethylene glycol solution (PEG) is often unsatisfactory as bowel preparation agent for colonoscopy. In order to provide equivalent efficacy with better patient tolerance, sodium phosphate tablet (SPT) has been developed. This study was carried out to compare the efficacy and compliance of two bowel preparation methods: PEG with ascorbic acid (PEGA) vs. SPT preparation. METHODS: A multicenter, randomized controlled trial was performed. Primary efficacy variable was overall quality of colon cleansing assessed by Boston bowel preparation scale (BBPS) during colonoscopy. Patient's satisfaction and adverse events were evaluated by means of symptom questionnaire completed by each patient immediately before colonoscopy. RESULTS: A total of 189 patients were randomly assigned to undergo pre-colonoscopic bowel preparation with either SPT (n=96) or PEGA (n=93). Overall BBPS score was 8.3+/-1.12 in the SPT group and 8.4+/-0.96 in the PEGA group (p=0.441). Among the 189 patients, 90 had polyps (47.6%) and 50 had adenomas (26.5%). The polyp/adenoma detection rate was 54.2% (n=52)/27.1% (n=26) for SPT group and 40.9% (n=38)/25.8% (n=24) for PEGA group (p=0.079 and 0.790, respectively). More number of patients were unable to take the prescribed dose of PEGA compared with the SPT regimen (8.6% vs. 2.0%, p=0.045). Overall satisfaction score was 7.9+/-1.63 in the SPT group and 7.4+/-1.53 in the PEGA group (p=0.022). CONCLUSIONS: Degree of colon preparation, polyp/adenoma detection rate and adverse effect were similar between SPT group and PEGA group. Patient compliance and satisfaction were greater in the SPT group.

Comparison of the Efficacy and Safety of Sodium Phosphate Tablets and Polyethylene Glycol Solution for Bowel Cleansing in Healthy Korean Adults

PURPOSE: Bowel cleansing is generally regarded as time-consuming and unpleasant among patients. Patients commonly state that bowel preparation provokes more discomfort than the actual colonoscopic examination. The purpose of this study was to compare two regimens of sodium phosphate (NaP) tablets versus polyethylene glycol (PEG) solution for bowel preparation in healthy Korean adults. MATERIALS AND METHODS: This was a single center, prospective, open-label, investigator-blinded, randomized, controlled-pilot study. A total of 62 healthy Korean subjects were randomly assigned to two groups (NaP vs. PEG). Efficacy, safety, and patient-related outcomes, as well as procedural parameters, were evaluated. RESULTS: Although there were no significant differences in total Ottawa bowel quality score, fluid scores and the rate of adequate bowel preparation were significantly better in the NaP group than the PEG group. Additionally, the NaP group showed better results regarding patient tolerance, satisfaction, preference, and rate of adverse events than the PEG group. Significant fluctuations in specific serum electrolytes were common and of a greater magnitude in the NaP group than the PEG group. However, these abnormalities were transient and did not result in serious complications and side effects. CONCLUSION: In this study, NaP tablets were shown to be an effective, well-tolerated, and acceptable regimen for bowel preparation. Also, our study suggests that NaP tablets may be safe and can be used as a bowel cleansing agent in healthy adults undergoing elective colonoscopy. Further multicenter, large scale studies are needed to confirm these findings.

The Evolution of Bowel Preparation and New Developments / 대한소화기학회지

Bowel preparation is essential for successful colonoscopy examination, and the most important factor is the bowel preparation agent used. However, selection of a bowel preparation agent invariably involves compromise. Originally, bowel preparation was performed for radiologic and surgical purposes, when the process involved dietary limitations, cathartics, and enemas, which had many side effects. Development of polyethylene glycol (PEG) solution led to substantive advancement of bowel preparation; however, despite its effectiveness and safety, the large volume involved, and its salty taste and unpleasant odor reduce compliance. Accordingly, modified PEG solutions requiring consumption of lower volumes and sulfate-free solutions were developed. Aqueous sodium phosphate is more effective and better tolerated than PEG solutions; however, fatal complications have occurred due to water and electrolyte shifts. Therefore, aqueous sodium phosphate was withdrawn by the US Food and Drug Administration, and currently, only sodium phosphate tablets remain available. In addition, oral sulfate solution and sodium picosulfate/magnesium citrate are also available, and various studies have reported on adjunctive preparations, such as hyperosmolar or stimulant laxatives, antiemetics, and prokinetics, which are now in various stages of development.

A Case of Complete Recovery from Late Insidious Type of Acute Phosphate Nephropathy / 대한내과학회지

The widespread use of colonoscopy for early detection of colorectal pathology has increased the use of osmotic laxatives for colonic cleansing. Among these, oral sodium phosphate preparations can cause renal insufficiency through the development of acute phosphate nephropathy. Acute phosphate nephropathy can be distinguished as early symptomatic and late insidious patterns. Patients whose presentation is insidious are easily overlooked and can progress to chronic kidney disease. We report a case of complete recovery from the late insidious type of acute phosphate nephropathy.
